Nitrogen-making equipment, simply speaking, is a kind of equipment that can be used to make nitrogen. Specifically, it is a machine and equipment that uses air as a raw material and uses some physical methods to separate oxygen and nitrogen in it to obtain nitrogen. So, a question arises, and that is: What are the methods for making nitrogen in industry? Next, in response to this question, I will make a specific explanation and answer to it so that it can be solved well.

In industry, the main nitrogen production methods of nitrogen production equipment include:

Method 1: Cryogenic air separation to produce nitrogen

It is a traditional method of making nitrogen, which first compresses and purifies the air, and turns it into a liquid state. Then, nitrogen is obtained through rectification. However, this method is not suitable for small-scale nitrogen production.

Method 2: Molecular sieve nitrogen production

Carbon molecular sieve is used as an adsorbent and the principle of pressure swing adsorption is used to obtain nitrogen. Its main advantages are simple process, high degree of automation, high nitrogen production speed and low energy consumption.
